B-vitamins are essential for energy metabolism, nervous system function, and red blood cell formation. Most budget B-complexes use cheap, synthetic forms that many people cannot convert effectively.
Our formula uses methylated B12 (methylcobalamin), active folate (methyltetrahydrofolate), active B6 (pyridoxal-5-phosphate), and riboflavin-5-phosphate — the forms your body can use directly.

Dosing Guide
How to take Vitamin B Complex — High Strength Active Forms
Take 1 capsule daily with breakfast. B-vitamins are best taken in the morning.
Always read the label. Consult a healthcare professional if you have any medical conditions or take prescription medication.
Quality & transparency
Why form matters
Medibro uses
D3 + K2 (MK-7 form)
Long-acting MK-7
Others often use
D3 alone or K2 as MK-4
Lower bioavailability
MK-7 has a 72-hour half-life vs. MK-4's 1-hour — meaning it's active in your system all week.
K2 directs calcium to bones rather than arteries. Without K2, high-dose D3 can lead to soft-tissue calcium deposits. MK-7 is the clinically preferred form.
